This can be difficult to read but try not to worry. If you have an overweight or underweight BMI your midwife and doctor will give you extra care throughout your pregnancy. There are also lots of things you can do to minimise the risks, such as staying active and eating well.

How much extra should I eat in pregnancy?

You don’t need to eat any extra food during the first 6 months of pregnancy. After that, you only need an extra 200 calories a day. This is about half a sandwich. Find out more about fun and healthy 200 calorie snacks.

The most important thing is to make sure you eat a healthy, balanced diet, which will help make sure you and your baby have all the nutrients you need.

There’s no need to eat for two or drink full-fat milk. Try not to let well-meaning family and friends persuade you to have any extra helpings and try to keep foods that are high in sugar or fat, such as sweets, crisps and biscuits, as occasional treats.

What exactly is a 'portion'?

It's not just what you eat that's important, it's how much you have of it. A portion is the amount of any one type of food you eat. For example, a fruit portion would be one apple or two plums. A vegetable portion would be a small side salad. Three heaped tablespoonfuls of cooked vegetables also count as a portion. Find out more about portion size.

Is it safe to diet during pregnancy?

Don't try to lose weight while you're pregnant as this is not healthy for you or your baby.[6] You and your baby may miss out on nutrients that you need to stay healthy and strong.

If you are concerned about putting on weight, remember that you will lose a lot of it with the birth of your baby and the placenta. And, if you have a healthy diet in pregnancy this may make it easier to lose weight after you have the baby.

Hello!
I had quite a low "healthy" BMI before getting pregnant (around 18.6) and am now at 21 weeks and have already put on 10kilos! I look slim but have a big bump! My midwife told me I should be careful not to put on too much weight, but I eat a healthy balanced diet and walk at least 1.5 hours per day. I feel worried but honestly don't know what - if anything - I should change! Thank you for your advice.

Hi,
It is great that you are keeping a healthy balanced diet and doing regular exercise, we do not advise for you to want to lose weight or actively diet. At this stage of pregnancy you do not need to be eating any more than you normally would do pre-pregnancy. If your bump is measuring bigger than expected then your midwife may need to refer you to have a growth scan to check on the size of the baby and the amount of water around your baby.
Best wishes

Thank you! My bump is a normal size, and i'm eating healthily and doing exercise every day so I'm just going to try not to worry too much about my weight.. Even if it does seem like a big gain already!! I guess it's just the way it is.

I’ve just found out im pregnant, unplanned, but a happy mistake.
Unfortunately I suffer from binge eating disorder and have a BMI >35. I’m taking 5mg of folic acid as per RCOG. I know that there are loads of risks associated, but I feel really scared and anxious due to my size, can larger people can still have healthy babies and healthy pregnancies?

Hi Liz
Yes, your weight can have an impact on your pregnancy- but that does not mean that it is always a negative impact. You may be at higher risk of certain things happening, but that does not mean that it will actually happen. Plenty of ladies who are overweight have successful pregnancies and healthy babies. You will have appointments with both your midwife and an obstetric doctor and you may be sent for a glucose tolerance test to test for gestational diabetes. Your midwife will go through all of this with you at your booking appointment (your first midwife contact.) Congratulations! Sophie,Tommy's Midwife

Hi,
Weight gain and pregnancy symptoms can vary hugely for pregnant women. Having no sickness can be normal , no everyone experiences this in pregnancy. With regards to your lack of weight gain, this will depend on your pre-pregnancy weight, but also how you are feeling during this pregnancy, how your appetite is. If this is your first pregnancy you should be having an appointment with your midwife round about now so do have a chat with her about your concerns.
